Today’s lifestyles frequently employ the assistance of electronics. From electronic alarm clocks to computers to air conditioners, toasters and other gadgets, humans are dependent on electronic devices.

The nineteenth century was the most promising in terms of studies on electricity. J. J. Thompson paved the way for studying electronics with the discovery of electrons inside the atom. From the minute electron to the large electronic gadgets that are used today, the science and technology of electronics has advanced in a big way.

The term electronics refers to the flow of electrons through various devices and materials. Capacitors store electric charges. There are analog circuits and digital systems in electronics, depending upon the type of transmission of signal. The signals vary continuously for analog circuits. Digital circuits involve signals 0 and 1.Vacuum electronic tubes and semiconductors are the two major milestones in the development of electronics. An electronic device normally has many components that impact the movement of electrons for specific applications. An average electronic device consists of the input and output systems along with processors that act on signals. Thus, electronics has revolutionized the world today and is inevitable everywhere. Who would have thought that the study of motion of a small electron would be so big one day?
